AES Bestand & Tekst Encryptor

Geavanceerde AES-encryptietool voor bestanden en tekst met ZIP-ondersteuning. Versleutel meerdere bestanden of tekst met AES-256, beheer je sleutels veilig en download versleutelde inhoud als ZIP-archieven. Perfect om je gevoelige documenten en communicatie te beveiligen.

Overview

This AES encryptor lets you encrypt and decrypt files or plain text using AES-256 — entirely inside your browser, with no server involved. Drop in any file type (up to 500 MB per file), type or auto-generate a cryptographically secure key, and download the result as a single encrypted ZIP archive or as individual encrypted files. Because the Web Crypto API does all the work locally, your files and your keys never touch a remote server, making this the right choice whenever you need to protect sensitive documents, source code, or personal data before sharing them over email or cloud storage.

Common Use Cases

  • Secure File Sharing — Encrypt confidential documents before attaching them to email or uploading to cloud storage, ensuring only the key holder can read them.
  • Personal Data Backup — Protect a batch of personal files — tax records, ID scans, medical documents — by encrypting them into a single ZIP archive before storing on an external drive or USB.
  • Developer Secret Storage — Encrypt .env files, API keys, or private certificates so they can be safely committed to a repository or handed off to a colleague.
  • Text Message Security — Encrypt a plain-text message to AES-256 ciphertext and share only the base64 output, decryptable by the recipient who holds the same key.
  • Encrypted ZIP Creation — Bundle multiple files of any type into a password-protected encrypted ZIP archive in one pass, without installing any software.

How It Works
1

Choose Operation Mode

Select whether to encrypt or decrypt data, and choose AES key size (128, 192, or 256 bits) and cipher mode.

2

Provide Key and Data

Enter your encryption key (or generate a secure one) and input the text or upload files you want to encrypt/decrypt.

3

Process and Download

The tool performs AES encryption/decryption locally and provides the result for download or copying.

Frequently Asked Questions

What is AES encryption?
AES (Advanced Encryption Standard) is a symmetric encryption algorithm used worldwide for securing sensitive data. It's the same encryption standard used by governments and banks for protecting classified information.

Which AES key size should I use?
AES-256 offers the highest security and is recommended for most use cases. AES-128 is faster but less secure. AES-192 is a middle ground but less commonly used.

How should I manage my encryption keys?
Keep encryption keys secure and separate from encrypted data. Use strong, randomly generated keys and consider using a password manager or secure key storage system.

Is my data secure during encryption?
Yes, all encryption and decryption happens locally in your browser. Your data, keys, and encrypted content never leave your device or get transmitted to servers.

Can I encrypt files as well as text?
Yes, the tool supports both text encryption and file encryption. You can encrypt documents, images, and other file types using AES encryption.

What happens if I lose my encryption key?
Without the correct key, AES-encrypted data cannot be recovered. Always backup your encryption keys securely and separately from your encrypted data.
